Tuning tips:

If you run at or above 5,000', start with a 130 main jet and your stock pilot jet. Around the 3,000' level we recommend a 135 main jet and 38 pilot jet, and at sea level --> 1,000' we recommend using a 140 main jet and 40 pilot jet.

Your system may vary slightly depending on your buggy and elevation, so it's good to get one size main jet above and below the recommended size above, along with a couple of regular NGK spark plugs for testing.

Spring and Dr Pulley Slider weight options info:

Buggy Owners: Most popular choices (and why!)

- 9g: For those who want maximum low end power for climbing and acceleration and do not care about top speed. Works best with the stock or yellow main spring. Aftermarket CDI encouraged to allow for more RPMs.- 10g: For those with a decent amount of hills to climb or want better low end power without sacrificing significant top speed. Works best with the yellow main spring. Aftermarket CDI a good idea.- 11g: Great all-around weight for a mix of hills and flat trail riding. Works best with the yellow main spring. Aftermarket CDI worth considering. - 12g: For mostly flat ground trail riding with occasional hills. Some low end gain, excellet top speed retention. Works best with the yellow or red main spring. Aftermarket CDI worth considering.

Scooter Owners: Most popular choices (and why!)

- 11g: Great all-around weight for a mix of hills and flat road riding. Our most popular weight for scooter owners. Works best with the stock main spring. Aftermarket CDI worth considering. - 12g: For mostly flat ground riding with occasional hills. Some low end gain, excellet top speed retention. Works best with the stock or yellow main spring. Aftermarket CDI worth considering.- 13g: Great weight for commuting and those who spend a lot of time at cruising speeds. Slightly better low end compared to stock weights. Possible top speed gain and lowered top speed RPMs. Works best with the stock or yellow main spring. Aftermarket CDI worth considering.

Note: Using Slider weights that are at the lower end of the weight scale can be too light to overcome the main torque spring tension (expecially wih the stronger performance main torque springs) before hitting the RPM limiter in the stock CDI (spark ignition unit). This can result in less top speed. You can typically get around this using a performance CDI unti with a higher RPM ceiling.
